Buy the hoop the professionals use. There's an old saying that you need to look under the hood to determine how good a car is. Well, look under the slick and shinny colors of my competitors hoops and you will find an inferior tubing that will not stand up to rigorous use in the home or at your fitness club. Almost all other custom hoops are made from 160 psi or 100 psi thin wall tubing. Canyon hoops are 25% to 50% more expensive per foot to buy, heavier, stronger and come with a no kink guarantee. Canyon Hoops have been designed to combine the ideal size and weight to help you lose weight, trim your waist line, build stamina, and improve your overall fitness level. Both the Regular adult 42" and the small adult 38" overall diameter Canyon Hoops are ideal for adult exercise and just plain fun. The large size and weight make these hoops easy to initiate and maintain the hooping rotation. The smaller the circumference of the hoop the faster you will need to rotate the hoop to keep it up. The 38" hoop, with a total circumference of 120 inches and a natural weight of 1.5 lbs, will take a bit more effort to maintain rotation but will give you more of an aerobic workout. Remember, you lose weight when you use oxygen, get your heart rate up, and burn calories. The 42" hoop, with a circumference of 132 inches, has a natural weight just under 2.0 lbs and since it is larger and heavier it is a easier to rotate and might be better for beginners or larger body types. I have had people ask me for a 4,5, even 7 pound hoops because they need to lose a lot of weight. THE WEIGHT OF THE HOOP IS NOT THE MOST IMPORTANT FACTOR IN WEIGHT LOSS!!! Adding weight will add some resistance but will slow the hoop down reducing the aerobic benefit of hooping. However, unlike other hoops you can add weight to Canyon hoops by simply adding water (1 cup water equals 1/2 pound) following the simple NO LEAK instructions until the hoop is the weight you prefer. The small adult hoop will accomodate 1 cups of water taking it to a maximum of 2 lbs, and the regular adult hoop will accomodate 2 cups water taking it to a maximum of 3.0 lbs. Canyon Hoops is the only custom hoop maker that uses a heavy duty 200 psi polyethylene tubing that is 25% heavier and stronger than all other hoops of similar construction. No amount of normal use will cause the hoop to kink, crack, bend, or crush. This hoop comes in a variety of colors and patterns to fit your personal style. If you don't see the color combination you like on the color choices listed please call and we will make a custom hoop for you at no extra charge. Any combination of two of the following: Red, White , Blue, Green, Orange, Yellow, Purple, Black, or Pink can be combined with the black hoop in a braided pattern to personalize your hoop. The 4 lb 8 oz weight on the listing is the packaged shipping weight of either size hoop. Thanks! Happy Hooping!
